Abstract.Any driver periodically, for example, after installing new tires or repairing the suspension, is faced with the need to perform an adjustment operation, commonly referred to as "toe-and-camber". However, even among the specialists and mechanics who produce this procedure, very few imagine the whole range of relationships between the angles of installation of controlled wheels and the properties of the wheeled vehicle to which they affect. When designing a wheeled vehicle, the kinematic matching of the steering gear and suspension is one of the most difficult tasks. It is necessary to simultaneously take into account a set of characteristics, including controllability, stability, and pass ability, as well as informative and sensitivity of the steering. In addition, this task includes the selection of optimal steerable wheel alignment angles and the calculation of the reactive force on the steering wheel, depending on the magnitude of the stabilizing moments and the resistance to rotation. The author of the article carried out a generalized analysis of the influence of installation angles on some operational properties, formulated positive and negative connections, the differences between the effects on the wheeled vehicle in the static and dynamic state. The shortcomings of the existing mathematical model for calculating the moment of weight stabilization are noted, and a new model of calculation is proposed that takes into account the influence of the longitudinal slope of the pin.

Abstract.It is offered a relatively simple way to determine the temporary dependencies of the bridge movement, or the cargo trolley of the bridge crane during the whole process of cargo movement, in which uncontrolled pendulum spatial swings of the cargo on the rope suspension is completely suppressed not only during braking, but also immediately after the acceleration of the bridge or cargo trolley. The method allows calculating the movement of cargo by means of a bridge or a cargo trolley in the direction of the bridge or cargo trolley, respectively, at a specified distance in the minimum time, including the curved spatial trajectory. The length of the cargo hoisting rope is assumed to be constant when moving. Temporary dependence of the angles of deflection of the cargo rope from the vertical allowed to obtaining on their basis the dependence of accelerations, velocities and movement of the point of suspension of cargo on the cargo trolley from time. The kinematic restrictions on movement of a point of a cargo suspension in the form of maximal achievable accelerations and speeds of a bridge and a trolley of a crane are considered. An example of application of the method in the form of temporal dependencies of the functions of changing the angles of the cargo rope in two vertical planes of the bridge movement and the crane truck, respectively. As well as temporary dependencies of the first two derivative angles and their corresponding linear movements of the point of suspension and cargo in space.

Abstract.In modern technology, gear-lever mechanisms are used that ensure a step-by-step rotation of the output link with a dwell operation without breaking their kinematic chain. In this case, the dwell of the output member in such mechanisms is approximate, and the known ways to increase its accuracy by eliminating or decreasing the angle of the reverse rotation of the output member do not provide proper results. This article offers several schemes of cam-toothed-lever mechanisms allowing to provide a precise and fixed dwell thanks to introduction of a resilient element into mechanisms with two-side preload pressure. The presence of the resilient element in the design of the mechanisms limits the acceleration of the output wheels and protects the mechanisms from a hard impact when the resilient element restores its original length, but at the same time it is the source of the oscillations of the output wheels of the mechanisms at the moment of the motion beginning after the end of the dwelling. The duration and amplitude of these oscillations, depending on the parameters of the resilient element, the friction in the kinematic pairs and the angular velocity of the crank, significantly affect the efficiency of the mechanism, and their evaluation is of undoubted interest.

Abstract. It is shown that one of the most promising methods of repairing the elements of the cooling system for engines of road-building machines is the use of thermoplastic polymer materials (hot melt adhesives). Examples of the determination of various parameters of polymeric materials using the methods of thermal analysis are considered. The technique for conducting a study of polymer materials used in the repair of the elements of the cooling system for road-building machines by the method of differential scanning calorimetry (DSC) is given. The essence of this method is described, which consists in heating the polymer material under study and recording as one or more parameters in the form of curves. With the help of the DSC method, the glass transition temperatures of the selected hot melt adhesives are determined. The results of experimental studies of the resistance of hot melt adhesives to the effect of elevated temperatures are presented. The analysis of the obtained graphs is carried out and it is concluded that the best temperature resistance is demonstrated by the materials of the brand Letek and MS-1. It is also established that after the second heating over 80°С and up to 220°С, the properties of the polymer material of grade МС-1 remain practically unchanged. This indicates that this material retains a long working capacity in this temperature range. The possibility of using the selected hot melt adhesives for repairing the elements of the cooling system for road-building machines is determined.

The purpose of the article is to describe the theoretical aspects of creating a methodology for ensuring the efficiency of the de-icing treatment of coatings. The article gives a definition of the concept of efficiency, outlines the main stages in the development of the methodology, presents the dependencies to be studied. The optimization problem formulated in this work is to maximize the efficiency of the anti-ice treatment of road (airfield) coatings. The criterion of optimality is such a technical and economic indicator of the work process as the cost of production. An indicator characterizing the quality of the working process is the uniformity of the application of the reagent. It is proposed to evaluate it by measuring the distance between the drops, which together form the spraying zone. The article considers the parameters that affect the hourly and operational performance, the uniformity of the reagent application. As optimized (variable) operational parameters, those are selected which can be easily changed directly during the distribution of the reagent: machine speed and reagent consumption. Scope of the technique: distribution of liquid, solid and wetted reagents by all produced models of road and airfield vehicles. The technique is intended both for selecting the modes of motion of the machines when planning and forming a detachment of reactant distributors, and for taking operational measures to ensure efficiency, taking into account the environmental conditions.

Abstract. This article presents the research results of the development of heavy soil, based on the use of magneto-striction exciters, taking into consideration its features with soil, which allows us to conclude the conditions necessary for the optimum and most effective mode of the magneto-striction vibrator. This is the conservation of the resonance frequencies of the working unit of the ripper, the change of which depends on the properties and volume of the developed soil. In the development of heavy soils with the help of external random influences on the loosening process, violates the mode of coordination of the working unit. Evaluation of the loosening processes shows that working with heavy soils when performing earthworks using the standard methods and mechanisms of loosening is not effective, while a more rational method is the method in which the intensification of the loosening process of the developed soil is determined by the high-frequency oscillation of the sound range. The application of this type of work activates the working units of the existing loosening machines, which allows to expanding the range of work produced by these machines on heavy soils.
